The National Medical Commission (NMC) had revised the NEET 2024 syllabus. As compared to the previous years' syllabus, some of the topics were removed from each of the three subjects, Physics, Chemistry and Biology. In the Biology subject, chapters have been removed in around six units. The following table brings the list of chapters and topics along with the units, which were removed in the NEET 2024 syllabus.

PGIMER does not accept the NEET UG score. You need to appear in the PGIMER BSc Nursing exam separately for the BSc Nursing program. To appear in this examination, students must have completed the Class 12 examination with Physics, Chemistry, Biology, and English subjects. A separate counseling will be conducted by PGIMER for granting admission to candidates on the basis of the merit scored in the entrance exam.
In the medical entrance test NEET, there can be 1 to 3 questions from this chapter. Some year, the Chemistry section of NEET has only one question from this chapter and in some other years, there can be 3 questions.
The following are the key concepts of this chapter: Compound, Elements, Rules, Law of conservation of mass, Addition and Subtraction, Atomic Mass, Law of multiple proportions, and Molecular Mass.
As the name suggests, the first chapter of the NCERT Class 11 Chemistry introduces various basic concepts of chemistry, such as the definition and importance of chemistry, atomic matter and molecular masses, the mole concept, laws of chemical combination, empirical, stoichiometry, and molecular formulas. It also includes the concepts of molarity and molality.
